Any way to "boost" briefly at power on? quick-start parameter? VZM31-SN

Switches General Discussion

Per this other thead, there was a “quick-start parameter” planned at some point? In this still happening?

Vzm31-sn inconsistent light bulb turn on and turn off at low light levels - Switches / General Discussion - Inovelli Community

I have a few chandeliers in particular with a bunch of bulbs. Have to set the low trim to a way-too-high value just to get all the bulbs to turn on reliably at lowest dim. I’d like to be able to dim below that, and the bulbs can certainly do it, they just can’t turn on at that level. Make sense?

edit: I should add that i’m using neutrals and trailing-edge mode.

You want to set the quick start time and quick start level. Params 23 and 24

I don’t see those listed here https://help.inovelli.com/en/articles/8189241-blue-series-2-1-switch-parameters, and if they should be, i’m unclear on how to set them via ZHA in Home Assistant. In here? Don’t see them.

It’s definitely P23 and P24, but you are correct they are not in the parameter listing on the help site. They’re not in the firmware change log either. @rohan will have to help w/ZHA.

I don’t use ZHA. @chack is the ZHA guy.

I also don’t see them in the changelog, were these only added to the 2-1? Know which release that happened with?

I think it was in 2.18. While the official docs haven’t been updated yet for it, here’s what it shows in Z2M: Inovelli VZM31-SN control via MQTT | Zigbee2MQTT

Thanks all for your help! For anyone else finding this thread, you can do it using zha-toolkit from HACS and then calling a service twice:

action: zha_toolkit.attr_write
data:
  ieee: 90:35:ea:ff:fe:c9:08:c7 (copy under Zigbee info on your device in HA)
  cluster: 64561 (the Inovelli cluster 0xfc31, converted to decimal)
  attribute: 23
  attr_val: "15" (lowest value that worked for me, without a noticeable flash)

action: zha_toolkit.attr_write
data:
  ieee: 90:35:ea:ff:fe:c9:08:c7
  cluster: 64561
  attribute: 24
  attr_val: "85" (lowest value that worked for me - depends on the bulbs i imagine)
